Propylthiouracil

Propylthiouracil (NSC 6498, NSC 70461) is a thyroperoxidase and 5'-deiodinase inhibitor, used to treat hyperthyroidism.

S0018

Verdiperstat

Verdiperstat (AZD3241, BHV-3241) is a selective, orally active and irreversible inhibitor of myeloperoxidase (MPO) with IC50 of 630 nM. Verdiperstat (AZD3241) can be used in the research of neurodegenerative brain disorders.

S6648

PF-06282999

PF-06282999 is an orally bioavailable, irreversible inactivator of myeloperoxidase enzyme and is currently in clinical trials for the potential treatment of cardiovascular diseases.

S0316

MPO-IN-28

MPO-IN-28 (Compound 28) is an inhibitor of myeloperoxidase (MPO) with IC50 of 44 nM.

S9874New

4-Aminobenzohydrazide

4-Aminobenzohydrazide (4-Aminobenzhydrazide, 4-aminobenzoic acid hydrazide, 4-ABAH, Myeloperoxidase Inhibitor I, NSC 640) is an inhibitor of MPO (Myeloperoxidase) enzyme that enhances iNOS induction in MPO-positive cells, but not in MPO-KO cells.

S5977New

3-Amino-1,2,4-triazole

3-Amino-1,2,4-triazole (1,2,4-Triazol-3-amine, 3-AT, Aminotriazole, Amitrol, 3-Amino-1H-1,2,4-triazole, Trapidil impurity B) is a common irreversible inhibitor of catalase, induces a compensatory mechanism for the hydrogen peroxide detoxification, which includs a rise in glutathione peroxidase (GPX) and glutathione reductase activities.

S4452New

ML162

ML162 is a covalent inhibitor of cellular phospholipid glutathione peroxidase (GPX-4) that induces ferroptosis.

S9803New

Elamipretide (MTP-131)

Elamipretide (MTP-131, SS-31, D-Arg-Dmt-Lys-Phe-NH2) is a cytochrome c peroxidase inhibitor. Elamipretide improves mitochondrial dysfunction, synaptic and memory impairment induced by lipopolysaccharide in mice.

S3274New

Glucosyl-vitexin

Glucosyl-vitexin (Glucosylvitexin), the major C-glycosylflavone present in millet, inhibits thyroid peroxidase (TPO) activity.

S3299New

Demethyleneberberine

Demethyleneberberine (DMB), a component of Cortex Phellodendri Chinensis (CPC), significantly alleviates the weight loss and diminishes myeloperoxidase (MPO) activity, while significantly reduces the production of pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor-α (TNF-α), and inhibits the activation of NF-κB signaling pathway. Demethyleneberberine (DMB) potentially ameliorates NAFLD (Non-alcoholic fatty liver disease) by activating AMPK pathways.

S0788

ML 210

ML-210 (CID 49766530) is a selective covalent inhibitor of cellular glutathione peroxidase 4 (GPX4) with EC50 of 0.04 μM and induces ferroptosis. ML-210 can selectively kill cells induced to express mutant RAS. ML-210 exhibits anti-cancer activity.

S4966

4-Methylesculetin

4-methylesculetin is one of the coumarin derivatives with great anti-oxidant and anti-inflammatory activities. 4-Methylesculetin inhibits myeloperoxidase (MPO) activity and reduces IL-6 level.

S8155

RSL3

RSL3 ((1S,3R)-RSL3) is a ferroptosis activator in a VDAC-independent manner,exhibiting selectivity for tumor cells bearing oncogenic RAS. RSL3 binds, inactivates GPX4 and thus mediates GPX4-regulated ferroptosis.

S3298New

Caulophylline (N-Methylcytisine)

Caulophylline (N-Methylcytisine, Caulophyllin, NMC) is a tricyclic quinolizidine alkaloid with anti-inflammatory activities. Caulophylline binds to nicotinic acetylcholine receptors (nAChR) from squid optical ganglia with Kd of 50 nM. Caulophylline significantly reduces myeloperoxidase (MPO) activity, blocks the activation of NF-κB by inhibiting IκB and IKK phosphorylation.

S6822

TMB dihydrochloride

TMB dihydrochloride (3,3',5,5'-Tetramethylbenzidine dihydrochloride hydrate, TMB-d, BM blue, Sure Blue TMB) is an excellent colorimetric substrate for detection of horseradish peroxidase (HRP) labeled probes and is used in staining procedures in immunohistochemistry and in enzyme-linked immunosorbent assays (ELISA).

S6106

3-Chloro-L-tyrosine

3-Chloro-L-tyrosine, a specific marker of myeloperoxidase-catalyzed oxidation, is markedly elevated in low density lipoprotein isolated from human atherosclerotic intima.
